basic information can be found here. These are date and time, the port
address, real frequency of measuring, the trigger settings. The
&#8220;Desired frequency&#8221; is prepared for future development and it is not
available in this version of application.<br><br><h3>&#8220;Current Position Info&#8221; Section</h3><br>The
information about the first displayed sample, amount of displayed
samples in the graph, and the total amount of measured samples can be
found in the first line. <br><br>The second line contents information
about the position of the mouse cursor in the measured data area if it
is relevant. The cursor position is relevant when it is above some
particular sample in the graph area.<br><br><h3>&#8220;Measured Data&#8221; Section</h3><br>The
measured data is displayed in this section. The labels used in the
process of configuration are displayed to help the user analyze the
data. It is recommended to use this tool to make the data mining more
clear and understandable. The graph area is sensitive to the mouse
cursor which means that information about mouse cursor in this area is
displayed in the &#8220;Current position Info&#8221; section. <br><br>It is
possible to put two &#8220;cursors&#8221; (blue lines in the graph) to mark some
particual positions. It can be done by clicking on the measured sample.
Discarding ht ecursor can be done by clicking on the cursor.<br><br><h3>&#8220;Navigator&#8221; Section</h3><br>This
section is split into two cooperating parts. The first of them is the
&#8220;navigation bar&#8221; which represents the complete collection of measured
data samples. The position of the window of data samples, which are
currently in the &#8220;measured data&#8221; section, is represented by red lines
in this &#8220;navigator bar&#8221;. The blue lines are representation of the
cursors if they are currently used. The detailed information about
cursors is described in the &#8220;Cursor Info Section&#8221;.<br><br>The second
part of this section is the part including the control buttons. It
allows the movement and zooming of the measured data are and the
adjusting of the sensitivity and accuracy of the data view.<br><br>Short specification of controlled buttons, which is available by tool tips as well, is following:<br><br><img style="width: 35px; height: 35px;" alt="" src="img/20.png">... Zoom in - it sets up higher sensitivity of displayed data, it implicates lower amount of displayed samples<br><br><img style="width: 36px; height: 35px;" alt="" src="img/21.png">... Zoom to fit area between cursors - only the complete set of data samples belonging to part between two cursors is displayed<br><br><img style="width: 37px; height: 37px;" alt="" src="img/22.png">... Zoom out - it sets up lower sensitivity of displayed data, it implicates bigger amount of displayed samples<br><br><img style="width: 37px; height: 36px;" alt="" src="img/23.png">... Discard cursors - both cursors are canceled<br><br><img style="width: 37px; height: 35px;" alt="" src="img/24.png">... Jump to the beginning - the measured data samples are displayed from the first sample according the sensitivity<br><br><img style="width: 36px; height: 35px;" alt="" src="img/25.png">... Go n* samples backwards - the displayed window is moved n* samples backward (direction to the first sample)<br><br><img style="width: 37px; height: 36px;" alt="" src="img/26.png">... Go n* samples forward - the displayed window is moved n* samples forward (direction to the last sample)<br><br><img style="width: 36px; height: 35px;" alt="" src="img/27.png">... Jump to the end - the displayed measured data samples (according to the sensitivity) including the last sample<br><br><img style="width: 36px; height: 37px;" alt="" src="img/28.png">...
Select a sample to jump to - the user is allowed to move the window to
the desired position of measured data sample according to the
sensitivity set up before. Following dialog is used to set the desired
value.<br><br><img style="width: 484px; height: 197px;" alt="" src="img/29.png"><br><br><h3>&#8220;Cursors&#8221;' Section</h3><br>The
&#8220;cursors&#8221; is the strong tool for data mining because it is very simple
to use and the result of the usage can be surprisingly fast and very
exact if the buttons are used meaningfully.<br><br>The user can set up
the cursor by clicking on the selected data sample and after the
successful action the blue line appears in the data section and in the
Navigator section as well. The position of relevant cursor including
information about the sample position and the value of the sample is
displayed in the cursor info part. If two cursors are adjusted then the
distance between these cursors is displayed in the related part
(cursors distance).</body></html>
